Although Lexi's mini dress is super short (maybe too short for a school dance?) she offsets the revealing-too-much factor with a high tank neckline. Her pretty heels are absolutely to die for and she finishes off her look with dangly bracelets and a simple classy clutch.

She wore her gorgeous long hair down in soft waves — no stuffy updo for this gal!

We're not sure how long she's been involved with the young gentleman, but he's giving Lexi a big kiss on the cheek with his arms circled around her waist, and she looks very happy about it.

Her mama, however, is either less thrilled about Lexi's date or she's close enough to him to tease him mercilessly.
